集会 (jí huì): to gather; assembly; meeting

The city government announced that a large gathering will be held in Central Park next week to celebrate the Spring Festival, with an estimated ten thousand participants.

The school stipulates that students may not organize any form of political assembly on campus without approval, or they will face disciplinary action.

Last night, hundreds of citizens spontaneously came to the square and held a peaceful assembly to demand that the government improve air quality.

Due to a sudden rainstorm, the outdoor gathering scheduled for this afternoon had to be canceled, and the organizers notified all participants via text message.
